Jonathan Schwartz | emailWeekdays 4 pm - 10 pm ETSaturdays and Sundays 6 pm - 12 am ETSchwartz has been a part of the Jam_ON family since its inception. When we let "The General of Jam" out of the studio, he's out seeing live music or dancing to his favorite Grateful Dead live CDs with his two daughters.

SiriusXM Program Director and low-end theorist Ari Fink fell in love with the bass at an early age, playing along to his mom’s Motown records until he was ready for the high school jazz band. A sucker for anything that grooves, Ari’s musical interests stretch across genres and eras, always in search of the *perfect* bassline. Once his PD responsibilities are completed each week, Ari turns up the late-night electro/funk vibes on Jamtronica Friday nights at Midnight ET, and returns to the Jam ON studios to host weekend afternoons 12-6 pm ET.
